Abstract

The invention relates to a MnP2O7 microcrystalline opacified matt glaze material composition having photocatalysis function and a preparation method thereof. The MnP2O7 microcrystalline opacified matt glaze material composition comprises the following components by mass percentage: 88-92% of powder A, 4-6% of MnP2O7 and 4-6% of kaolin; wherein the powder A comprises the following components by weight: 12-14% of SiO2, 4-6% of Al2O3, 47-49% of P2O5, 1.5-2.5% of MnO, 12-14% of Li2O, 6-8% of Na2O, and 11-13% of K2O. According to the invention, MnP2O7 is firstly introduced in preparation of a glaze material, the surface crystallization and decorative effect of a glaze layer are good, and the toxic gas degradation through photocatalysis is excellent.

Description

technical field [0001] The invention belongs to the technical field of ceramic glazes, and relates to a method for preparing surface glazes of architectural sanitary ceramics, in particular to a photocatalytic function MnP 2 o 7 The invention discloses a method for preparing a microcrystalline opacified matt ceramic glaze. The surface of the glaze prepared by the method has an excellent function of photocatalytically degrading poisonous gas, has a good opacifying decorative effect, and has a strong covering ability. And under sunlight conditions, it can effectively decompose toxic gases in the air such as benzene, sulfur dioxide, ammonia, etc., which is of great significance to the purification of the home environment. Background technique [0002] The toxic organic substances or gases released by various chemical products in the environment we live in are still difficult to avoid at present, and they are potential threats to human health. Therefore, in order to avoid pois...
